# Translate given SubX files with debug information on Linux.
#
# Mu provides 3 canonical ways to translate unsafe SubX programs:
#   0. The C++ translator 'bootstrap translate' can generate traces for
#   debugging on Linux or BSD or Mac, but doesn't support any syntax sugar.
#   1. The self-hosted translator can be run natively on Linux using
#   'translate_subx'. It is fast and supports all syntax sugar, but you get no
#   trace for debugging.
#   2. The self-hosted translator can be run emulated on Linux or BSD or Mac
#   using 'translate_subx_emulated'. It supports all syntax sugar. However, it
#   can be slow if you generate traces.
#
# This script fills in the gap above by stitching together aspects from
# multiple approaches. It translates syntax sugar natively, but emulates lower
# levels using the C++ translator. The result is complete and relatively fast
# even when generating traces.
#
# The cost: it needs Linux. There is no script to generate traces while
# running emulated on BSD or Mac. That's often impractically slow.
